Abstract:
Studies were conducted to evolve suitable techniques of mass culture of
Fusarium oxysporum Schlect infecting the rice brown plant hopper. The results
showed that green gram, wheat or sorghum could be used as substrates for eosy
mass production of the fungus as they produced maximum spores with high
virulence. Further, for better growth and sporulaticn, a combination of 30 g of
material +25 ml of water was found to be the optimum.
